| Register EPackage in Xcore programatically in Standalone [message #1782143] |

Hello,
I am trying to access the EPackage inside an XCore, so I can register it and load models that conform to the metamodel defined using xcore. This should work both when invoked from an Eclipse as in standalone (i.e. register the metamodel from a non-eclipse java application)
So far I have done:
ResourceSet resourceSet = new ResourceSetImpl();
resourceSet.getURIConverter().getURIMap().putAll(EcorePlugin.computePlatformURIMap(true));
resourceSet.getPackageRegistry().put(XcorePackage.eINSTANCE.getNsURI(), XcorePackage.eINSTANCE);
Resource metamodel = resourceSet.createResource(locationURI);
metamodel.load(Collections.EMPTY_MAP);
EPackage ePackage = (EPackage)EcoreUtil.getObjectByType(metamodel.getContents(), EcorePackage.Literals.EPACKAGE);
Currently I am getting an exception in the createResource call:

The stack trace also suggests that in a standalone scenario I would need to add some "ui" dependencies, even though my java application does not do any UI per se.
Thanks for any info or pointers.

Hi Ed,
Thanks for the information.
Yes, you are right that was from an Eclipse instance. I try the standalone setup for plain Java.
In the case of a UI present, any pointers on the error? My plugin has a dependency on xcore, but not on xtext. Do I need to also depend on xtext (and any other plugins?).
Cheers,
